Your question: Can adults have germ cell tumors?

Extragonadal germ cell tumors are usually seen in children or young adults and typically arise in midline locations. In adults, the most common sites of primary extragonadal germ cell tumors are, in descending order, the mediastinum, retroperitoneum, and cranium.

Who gets germ cell tumors?

Ovarian germ cell tumors usually occur in teenage girls or young women and most often affect just one ovary. The ovaries are a pair of organs in the female reproductive system. They are in the pelvis, one on each side of the uterus (the hollow, pear-shaped organ where a fetus grows).

What are the signs of germ cell tumor?

Common signs of germ cell tumors include:

  • A mass on your ovaries or testicles.
  • Belly pain and swelling (caused by tumor)
  • Bathroom troubles (a hard time pooping or holding in your pee, if the tumor is near your pelvis)
  • Breast growth, pubic hair, or vaginal bleeding at an earlier age than normal.
  • Belly or chest pain.

What is the survival rate of germ cell tumor?

The 5-year survival rate for teens ages 15 to 19 is 93%. The survival and cure rates also depend on several factors, including the stage of the disease. The cure rate for children with a stage I or stage II germ cell tumor is 90%. The cure rate for a stage III tumor is 87%.

What is the most common germ cell tumor?

Teratomas are the most common type of germ cell tumor to develop in extragonadal (not in the ovary or testes) areas. Doctors usually treat teratomas with surgery because chemotherapy doesn’t work in a benign tumor.

Can germ cell tumors be benign?

Most germ cell tumors in the ovaries are benign (not cancer). Rarely, the tumors are malignant (cancerous). Ovarian germ cell tumors usually develop in young women under 20, but they can grow in older women, too. Most often, a tumor only grows in one ovary.

What percentage of germ cell tumors are malignant?

Malignant germ cell tumors of the mediastinum are uncommon, representing only 3 to 10% of tumors originating in the mediastinum. They are much less common than germinal tumors arising in the testes, and account for only 1 to 5% of all germ cell neoplasms.

Can germ cell tumors spread?

Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes, and central nervous system. Rarely, germ cell tumors can spread to the bone, bone marrow, and other organs.

Do germ cell tumors grow fast?

There are two types of germ cell tumors that start in the gonads, or reproductive organs: seminomas, which are slower-growing, and nonseminomas, which are faster-growing tumors.

Are germ cell tumors curable?

Germ cell tumours generally respond very well to chemotherapy and most people are cured. Even cancers that have spread are still very treatable with chemotherapy.

Are germ cell tumors cancerous?

Germ cell tumors are growths of cells that form from reproductive cells. The tumors may be cancerous or not cancerous. Most germ cell tumors occur in the testicles or the ovaries.

What is a mixed germ cell tumor?

Listen to pronunciation. (mikst jerm sel TOO-mer) A rare type of cancer that is made up of at least two different types of germ cell tumors (tumors that begin in cells that form sperm or eggs). These may include choriocarcinoma, embryonal carcinoma, yolk sac tumor, teratoma, and seminoma.

Can teratomas be malignant?

A malignant teratoma is a type of cancer consisting of cysts that contain one or more of the three primary embryonic germ layers ectoderm, mesoderm, and endoderm. Because malignant teratomas have usually spread by the time of diagnosis, systemic chemotherapy is needed.
